I think you are still generalizing, say you bring me in your project, is your job to let me know how to integrate in your tools, there are too many tools out so I can learn them all. Like in Web when we bring a new developer we don't expect them to just start coding , maybe they did not used gulp but some other similar tool, maybe they did not used less but used css. I am not sure why you would generalize that most Java developers can't use CLI tools or a VCS, there are some bad developers in the world and some of them are also writing shit in cool languages and spam everywhere some toy project like a TODO app and you see it upvoted just because is in Rust/GO or Shiny.js 7.0
